Embodiment 1
[0033] A medicament for treating municipal domestic sludge, the composition of which is calculated by mass percentage:
[0034] 5% of mineral powder, 10% of bleaching powder, 6% of PAC with a salinity of 50%, 76.6% of zwitterionic polyacrylamide, 2% of silkworm excrement and 0.4% of sewage treatment bacteria, of which:
[0035] Mineral powder, bleaching powder, PAC, PAM and silkworm excrement must pass through a 50-mesh sieve before use.
[0036] Silkworm excrement is used after being coated with carboxymethyl chitosan, the ratio of silkworm excrement and carboxymethyl chitosan is 100:5 by weight, after spray drying, carboxymethyl chitosan is coated on the surface of silkworm excrement,
[0037] Sewage treatment strains are special strains for waste water treatment, trade name: Nitrate (nitrifying bacteria), manufacturer: Dongxing Defeng Biotechnology Co., Ltd.
